Closures, Objects, Actors, and Picos

Tue Oct 13 10:50:00 2026

I've been intrigued by closures since I taught introductory computer science from SICP at UC Davis in 1988. This post dives into a little programming language theory to trace a line from closures to objects to actors to picos, showing what each step adds. A pico is a closure that has been made to answer for itself in the world, with persistent state, a durable identity, and relationships it can carry when it moves.

Using Picos for BYU's Priority Registration

Wed Jan 4 12:15:00 2017

Picos are a natural way to build microservices. This post presents the results of an experiment we ran to see how the new Pico Engine performs when placed under surge loading that simulates BYU's priority registration.

A Pico-Based Platform for ESProto Sensors

Mon May 2 16:36:00 2016

Spimes are a wonderful intellectual framework for thinking about the Internet of Things. This blog post shows how spimes can be created using picos and then applied to a sensor platform called ESProto.

Reactive Programming Patterns: Examples from Fuse

Tue Apr 5 17:23:00 2016

Reactive programming requires new programming techniques and methods. This post describes common patterns in asynchronous reactive programming and gives examples from the open-source code base for the Fuse connected car platform. While the examples below are based on the pico platform, they are equally applicable to other Actor-based reactive programming platforms like Akka.

Reactive Programming with Picos

Tue Nov 17 11:50:00 2015

This is an introduction to picos as a method for doing reactive programming. The article contains many links to other, more detailed articles about specific topics. You can thus consider this an index to a detailed look at how picos work and how they can be programmed.
